If you've been considering jumping ship from your current carrier and hopping over to Sprint, you may want to finalize that decision before June 23, 2011. Why is that, you ask? Because until that date, Sprint will give you $125 per line if you port your existing number over (with a qualifying smartphone or data plan, of course). That's right, you will get paid to switch carriers.

Here's how the deal works: buy a new smartphone from Sprint's online store, transfer your number over (you should be prompted to do so during checkout), and register for your credit within 72 hours of activating your phone.

One neat feature of BlackBerrys is that when you put the phone in its case, the screen automatically shuts off. The effect is only part novelty; after all, by shutting the screen off sooner, you're saving battery (although in all honesty, it's doubtful you're saving that much battery).

You may be in luck, as Sprint is generously offering a $125 credit for smartphone subscribers who make the switch and port their old numbers to Sprint.

One of the more obvious settings missing from Android is the ability to use one keyboard, say Swype, in portrait orientation, and then automatically switch to another keyboard when the phone is in landscape.

This feature has been oft-requested, and is something that is strangely missing from many mobile OSes. Well, the clever clogs over at the XDA-Developers Nexus One forum have managed to figure it out with a little workaround.

One of the most vaunted features of webOS was its decidedly pretty multitasking interface. Users could invoke an overlay of thumbnail “cards” of their running applications and switch to or close them.

Fresh onto the Android Marketplace is Visual Task Switcher. Continuing on from some progressmade earlier this year (although probably not using the same method), this application grants you thumbnail application switching. While not as polished as Palm’s version, this is an encouraging step towards that alluring goal.
